This question may well be subjective and may well be closed for it but it's a question i've been dying to ask since this site was proposed:
What are some signs that you're up against a set.
Let me give you one scenario where it worked out in my favor. I was playing $1-$2 when I picked up AJ-heart suited and limped in on the button. My stack was about $250 I think p1 was about $75, can't remember p2's stack size. Three players to the flop and it comes down A-J-2 (forget the suits it was forever ago - but rainbow for sure).
p2: min or 2 blind raise
me: re-raise 2-4 more blinds.
p1: re-re-raises all in.
well I hemmed and I hawed and I eventually called. He just didn't seem like he had it. When I didn't call or fold instantly his reaction just didn't quite seem right. In the end I called him to find he had A-2 for a worse 2-pair.
I lucked out that time. And I wondered for a while before calling if he had a set.
This is by far the weakeset part of my game. Any pointers on how to sniff out sets a little better is greatly appreciated.
Also, please don't tell me that I should have folded in this situation without some details as to WHY I should've folded.
